CAMERA.

Application filed .Tu 1y 29, 1916.

To all 107mm it may concern.'

.lie it known that ne, (laut llonNMaNN and ,lil/,im (nl. (linnn, bothcitizens ot the United States, and both 'residents of the city ofBinghamton, county ot Broome, and State ot New York, have, inventedcertain new and useful lnilirovements in (lameras, of which thefollowing is a specification reference beurer had drawings.

This invention is an improvement upon that tor which we liledapplication t'or `lietfters Patent ot the United States December 1i',1915, Serial No. 137,31-l, to which we reter for a more completedisclosure ot' the details ot etnstruction and operation of themechanism other than that immediately involved in this invention.

The purpose of this 7 to the aeeoniiunrving present invention, the

saine as that oi.' the former one, is tofprof vide a camera with meanswhereby the teeding` of the iih'n :t'or making successive exposures maybe automatic and yet under the perfect control o1 the operator, wherebygreat speed in the making oi exposures is possible; and our formerapparatus was provided, among other'things, with an indicator whichdisclosel the number otl exposures that had been Inadeon any given lihnand`eonsequently the amount of unexposed lm yet available to theoperator for additional exposures; but that. index was operated solelyby the motor and only when it effected the inoven'ient of the lilm, sothat if the operator at any time desired to make an exposure by hand,then inasmuch as the indicator wasl only operated when the motor wasused, there was of course no record produced oi such hand made eX-posure; consequently if the operator forgot to advance the4 indicatorcorrespondingly with the number ot his hand made expo sures, then theindicator instead ot being,r a guide correctly notifying the operator ofthe condition of his apparatus, might become ail'irn'iativelymisleading, resulting in faulty, it not valueless exposures.

lt. is the purpose oi' this present invention therefore to equip anapparatus ot the classl statedwith parts soconstructcd and Patented Feb.20, 191.?. serial No. 111,981.

associated together that the' indicator will properly recordl anyexposure, whether efieeted through the instrumentalit)r of the motor orb v hand, thus under all cireumstances serving' as a safe guide to theoperator.

bReferring; to the drawings, Figure 1 is an elevation Qt the side ot a.folding camera embodyingk our invention` the cover plate whichwiltordinaril7 protect the mechanism being;` removed; Fig. i is avertical sectional view, soi-ne ot'the parts being` shown in elevation,taken on the line 1`-1 of Fig. 1; Fig. 3 is a longitudinal detail partlyin elevation showing the parts more immediately involved in thisinvention.

.ln the drawings, l. represents the body of the camera, 2 the removableback, 3 one ol the supports tor the usual carrying handle, at thewindingl spool, 5 the deliveryspool, the spindle for the wintling`spool, 7 the knurled thunibnut on the end of the spindle 6 whereby itmay be conveniently turned by hand, 8 the motor, in this Case a spring',as fully explained in said application. t) the shaft tor the motor, 10the pinion on the end ot' the shaft, it being,r the main driving;` rearof the apparatus, 11 the trip piner lever whereby the motor is releasedand stopped. 12 the ehain ot gearing, 13 the. escapemeut. Il thevibrator. 'l`hese last two parts ditl'er slightly troni the constructionshown in said pending' application but their functions are the uponwhich we ot gearing'.

ln our said previous invention the indicator plate ,was placed at thelower end of the chain of gearing und was actuated step by step by apawl connected with and oper ated by the level 11, so that it that leverwas not moved, which would be the case it' the winding spool wasactuated by hand instead ot' by the motor, then there would be nomovement of the indicator disk, hefiee one or more exposures .wonld havebeen. made without any record thereinv Under this present constructiontherefore we trans pose the indicator trom the lower or tail end of thechain ot' gearing to or near t0 the same. 1ro-is the base plate preterto support the chain i opposite end and supplement it by added partswhich will now lows: i 4

As stated above, 6 is the center for the winding spool. lts constructionand method of operation are now so well understood as not to requireexplanation. 7 is the knurled thumbnut on its exposed outer end wherebyit may be turned by hand. 1G is a. small pinion mounted on and whichturns with the spindle 6, and it gears into a larger gear 17, which isloosely mounted on the axis 1S of the larger gear 19, which is driven bythe pinion 20, which latter is preferably integral lwith it, by the maindriving gear 10 on the motor shaft. The axis 18 is pre. ierablysupported upon the base plate by the threaded extension Q1 thereof.

22 and 23 are mere spacing washers lo cated between the gears. 24 is agear on` the center 6 whereby, as explained in said application, thetake-up spool is rotated when the motor is employed. 25 is the indexplate. 1t is provided, as seen best in Fig. l, with a series ofnumerals, in the present instance y1 to 12. Other designations and ofany desired number may be employed.

The index plate be described, as foly upon the outer surface f the gear17in located between the gear motor 'is used motor is usedfall suchmanner that it may be turned thereon. We prefer to employ spring fingers26 17 and the dial plate and so arranged in any known way that'the dialplate'will be frictionally held on the gear. "We also provide the dialplate with a raised'web or linger plate 27 whereby it may beconveniently turned. The spring friction iingers 26 may, if desired, beattached to the gear 17 and so shaped that they wiil take i thenecessary frictional bearing 28 is a washer or equivalent device whichholds the gear 1G in The operation is obvious. "When the its drivingpinion l0 will rotate the pinion 2.0 and tbc lai-gc gear 19, whichintegral with the latter, and it in turn will rotate the gear 2li andthrough it 'the spindle of the take-up spool, to which it is connected,in the manner explained in said pending application, whereby the spindlemay be rotated by hand without rotating 'she chain rolia gearing, sothat when the two gearsi and Q4 will likewise rotate, that is to say;the washers Q2 and 23, the gears 16 and 1 7, the dial plate and theknurl'ed tbumbnutfl, will all simultaneously rotatev tov the extent thatthey are driven by the,`

n'iotor. lNhen, however, it is desired to turn tnewinding spool, eitherfor the purpose of making an eA )sure or otherwise, thenby ump ue-6and-tbe winding spool.

Apeculiar 25 is suitably supported parts associated with these ii'ion ofthe knurled thumbconnected with it. will be rotated in the G5 samedirection as before, but owing to the connection between the gear Q4 andthe spindle there will be no rotation ol' the chain of gearing. but thegear lli. which is rast upon the spindle (i, and through it the F gear17 carrying the dial plate 25 with it, because oic thefrictionalconnection between the two, will be rotated, so that the dialplate will properly register the number oi expolsures made, whether thetake-np spool has been operated by the motor or by hand, and

thus a correct record will be made whereby the operator may know withassurance the position oil` his libn.

It will be. obvious to those who are familiar with such mat-ters thatmodifications may be made in the details of construction and to' someextent their method o'l combination and yet the essentials of theinventionv be retained. le therefore do not limit ourselves to thatwhich we have herein dcs'cribed and illustrated which shows one formonly in which our invention may be constructed. i i
